Approximately one in eight couples fail to conceive after one year of trying and seek medical treatment for infertility, researchers note in European Urology. For the current analysis, researchers examined data from 61 experiments that tested the effectiveness of a wide range of drugs and supplements for improving semen parameters and the odds of a live birth. They looked for improvements in three things that can make conception more likely: sperm concentration, or the amount of sperm released when men ejaculate; sperm morphology, or the number of sperm in the ideal size and shape with an oval head and a long tail; and motility, or the ability of sperm to move through the female reproductive tract to reach an egg.
Are you ready to start having kids, but worried your sperm count is too low? Semen is most likely to be fertile when it contains more than 15 million sperm per milliliter. That count can go down when your testicles get too hot, when you're stressed out, and when you have an STI that's interfering with sperm production. Luckily, there are many steps you can take to boost your count.
Healthy sperms are an important factor in male fertility. Sperm count is referred to the average total number of sperm present in one sample of semen. According to recent World Health Organization guideline, a healthy sperm count is 15 million per milliliters ml or 39 millions per sample.

This measures many features of the sperm and semen the fluid in which the sperm are contained. The most important of these are the number of sperm sperm countmotility of the sperm percentage of moving spermmorphology of the sperm percentage of normally shaped spermand the volume of fluid. To assess sperm morphology, the sperm are examined under a microscope and the percentage of abnormally shaped sperm is estimated.
Back to Health A to Z. A low sperm count, also called oligozoospermia, is where a man has fewer than 15 million sperm per millilitre of semen. Having a low sperm count can make it more difficult to conceive naturally, although successful pregnancies can still occur.
In an age when a small quantity of sperm can lead to pregnancy through in vitro fertilization or intracytoplasmic sperm injection, selecting healthy sperm is important. Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling TUNEL and the alkaline comet test are SDF tests that directly measure DNA damage and have shown closer correlations with assisted reproduction results than indirect tools such as the sperm chromatin structure assay or the sperm chromatic dispersion test. It is difficult; however, to endorse a single test as the best test overall; instead, it is best to select a testing method based on each patient's clinical condition and goals.
